The conditions ML ║ NO and LO ≅ MN are sufficient to show that the LMNO is a parallelogram.
It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a parallelogram, opposite sides are parallel and equal. And its diagonals are not equal but intersect at the mid-point.
The side ML is parallel to the NO that is given as
ML ║ NO
And the side LO is equal to the side MN
